Abstract Here, we report a new semi-organic single crystal namely Bis(picolinic acetate) Zinc(II) (BPZ) which was grown by a conventional slow evaporation method at room temperature. Structural studies were carried out by single crystal XRD and the results show that Bis(picolinic acetate) Zinc(II) belongs to monoclinic crystal system with space group P21/n. The presence of functional groups in the grown crystal was identified by FTIR spectral analysis. UV-Vis spectral studies reveal that the grown crystals are transparent in the wavelength region of 200-1200 nm. In order to analyze the mechanical strength of the grown crystal, Vickers micro hardness tester was employed. The dielectric properties with respect to different frequency at room temperature were also studied to analyze the dielectric response. The third order nonlinear optical properties were determined by Z-scan studies which shows significant higher values of nonlinear absorption coefficient (β) and third order nonlinear susceptibility (χ3). The enhanced third order nonlinear behavior suggests that the title compound is suitable for nonlinear optical applications.

用于三阶 NLO 应用的半有机双（醋酸吡啶甲酸）锌（II）单晶的生长和 Z 扫描分析

摘要 在这里，我们报告了一种新的半有机单晶，即双（醋酸吡啶甲酸）锌（II）（BPZ），它是在室温下通过传统的缓慢蒸发方法生长的。通过单晶XRD进行结构研究，结果表明Bis(picolinic acetate)Zinc(II)属于空间群为P21/n的单斜晶系。通过FTIR光谱分析鉴定生长晶体中官能团的存在。UV-Vis 光谱研究表明，生长的晶体在 200-1200 nm 的波长范围内是透明的。为了分析生长晶体的机械强度，采用维氏显微硬度计。还研究了室温下不同频率的介电特性，以分析介电响应。三阶非线性光学特性由 Z 扫描研究确定，其显示非线性吸收系数 (β) 和三阶非线性磁化率 (χ3) 的值显着更高。增强的三阶非线性行为表明标题化合物适用于非线性光学应用。
